Writing linear equations

Writing linear equations

in slope intercept form given two points

Fill in the Blank

Given points (-2,8) and (2,-12) determine the slope of the line. (change in y over change in x). Be sure to simplify.

Multiple Choice

Given points (-2,8) and (2,-12)
and using point (-2,8) what is the point slope equation of the line --                                use (y - y1) = m(x - x1)

• y = -5

• (y - 8) = -5( x + 2)

• -12-8 = -5(2 - 2)

• (y + 8) = -5(x - 2)

Multiple Choice

Given points (-2,8) and (2,-12)

and using point (-2,8) what is the equation of the line in slope intercept form. y = mx + b

• y = -5x - 18

• y = 5x + 18

• y = -5x + 2

• y = -5x - 2

Multiple Choice

• -3

• -4/5

• 4/5

• 3

Multiple Choice

What are the slope and y-intercept of the graph

• slope -1/2. y-int 1

• slope -2. y-int 2

• slope 1/2. y-int 2

• slope 2. y-int 1

Multiple Choice

• m = 75 - 15d

• m = 108 - 3d

• m = 90 - 6d

Multiple Choice

• y = -48x + 2

• y = 48x + 2

• y = 2x + 48

• y = 2x - 48

Multiple Choice

What is the equation of the line shown?

• y = -3/2 x -2
